it seems to be a really nice machine, so slim!
I used to run only linux on this kind of machine but never played gentoo. I guess it 'll work fine._________________LinuxPPC user!

Yeah, however as usual with server class hardware the power consumption is through the roof, at least it sais so in the specs (500W at full load). NOT good when compiling a lot._________________Please put [SOLVED] in your topic if you are a moron.

I got my machine with no OS installed thus I did a linux installation by myself on that unmanaged and headless POWER machine.
I don't have any HMC or other IBM goodies for my power hungry machine (9123-710) and i went by serial console. Only few days ago i acquired a GXT135P (but I still use it only over ssh). I read a lot of IBM Redbooks!

I suggest to you use the IBM Diagnostic CD (AIX based) and to go for a firmware (microcodes) update on IBM support website.
After that... let's go with linux!_________________LinuxPPC user!
